mit greasing oi pans of different dimensions, it

being customary to connect together a series'of pans by connecting bars so that they are equidistantly spaced, wherefore the spacing of centers of the ypans will vary with the dimensions thereof.V

To each of the outermost bearing brackets 4%!` and the central bracket 48 is fastened an arm 64 which carries a roller 66 engaging the back of the Y rack 42 to guide the same as it slidesto and fro on the bearing brackets whereon it is supported.

A'cover 10 is supported on the angle bars T2 connecting the end frames 36 and is provided with a longitudinal slot 'I4 through which the spindles 46 project upwardly. Collars 15, on which arerotatably mounted thesleeves 16 y.which revolveV on roller bearings (not shown), are fastened on the portions of the spindles projecting into slot '|4.

The collars '|5 haveY circumferential flanges I1 on Vthat the bases of motor l0 and the reduction unit |2312. The outlet check valves are connected Vby Y tubes |24 to the respective nipples 94, 98 and |03 their upper ends, which are provided `With dix.

ametrically extending driving lugs or Yribs 18 formed-on their top faces.' These ribs V'I8 are adapted to engage with transverse slots'll in the f bases of the brush heads 82 and thereby drive the latter. VThe construction of kthe brush heads and'vv the attachment of theibristles 84 thereto is Ysimilar Vto that shown'in the patent to W. F.

Dehufl, No. 1,899,316, issued Feb, 28, 1933, Where.- fore further description thereof is deemed un` brush heads has a vertical bore 85 whose lower` end admits the upper end of the V4spindle Whereon it is` supported and a metal tube (not shown) necessary, but it may be noted that each of the of the bearing brackets. The tubes |24 are secured' on the protruding ends of the nipples |2| v by'cla'mping rings |25 threaded on the nipples. v lThe construction of the inlet check valves is similar except Vthat the spring is seated against the'sleevercorresponding to the sleeve |22 and holds the ball down against an internalshouldercorresponding to the shoulder |235. When the. pistons l0 ascend" in their bores 1| 03 they Y create suction in the latter and the balls of their inlet check valves are 'forced upwardlyand the grease is sucked from sump! I6 through the inlet check valves and intake ducts ||2 into the bores |08. Then .when the pistons ||0 descend, the

Y balls of'the inlet check valves are iclosedjand grease is forced'through the outletj'ducts` |20 and past the balls |22 of the outlet checkvalves into Y the tubesv |24 which Vdeliver' the grease :to the secured in the upper .end of the bore and projecting downwardly into the interiorof the brush spindles. "The Vdetails. of Yconstruction just men?l f tioned areV similar. to patent. L VBefore mounting those shown 'in' the Dehui .the brush heads with their slots 80 indriving engagementwith the drivingV lugs 18, a cover plate4 06 having'spaced holes corresponding to the spacing of the spindles is placed Yupon cover 10 with thesleeves 1,6 disposed in said holes; It'may be noted that a. setzof cover plates 801s provided having variousy spacingsin its 1 holes corresponding to variousadjusted positions ofthespindles.
